Last week I purchased a burger at Burger King for $1.58. The
counter girl took my $2 and I was digging for my change when
I pulled 8 cents from my pocket and gave it to her. She
stood there, holding the nickel and 3 pennies, while looking
at the screen on her register. I sensed her discomfort and
tried to tell her to just give me two quarters, but she
hailed the manager for help. While he tried to explain the
transaction to her, she stood there and cried.. Why do I
tell you this? Because of the evolution in teaching
math since the 1950s:
Teaching Math In 1950s
A logger sells a truckload of lumber for $100. His cost of
production is 4/5 of the price. What is his profit?
Teaching Math In 1960s
A logger sells a truckload of lumber for $100. His cost of
production is 4/5 of the price, or $80. What is his profit?
Teaching Math In 1970s
A logger sells a truckload of lumber for $100. His cost of
production is $80. Did he make a profit?
Teaching Math In 1980s
A logger sells a truckload of lumber for $100. His cost of
production is $80 and his profit is $20. Your assignment:
Underline the number 20.
Teaching Math In 1990s
A logger cuts down a beautiful forest because he is selfish
and inconsiderate and cares nothing for the habitat of
animals or the preservation of our woodlands. He does this
so he can make a profit of $20. What do you think of this
way of making a living? Topic for class participation after
answering the question: How did the birds and squirrels feel
as the logger cut down their homes? (There are no wrong
answers, and if you feel like crying, it's ok.
